You have a higher risk for diabetes if you have any of the following:

  • Age greater than 45 years
  • Diabetes during a previous pregnancy
  • Excess body weight (especially around the waist)
  • Family history of diabetes
  • Given birth to a baby weighing more than 9 pounds
  • HDL cholesterol under 35 mg/dL
  • High blood levels of triglycerides, a type of fat molecule (250 mg/dL or more)
  • High blood pressure (greater than or equal to 140/90 mmHg)
  • Impaired glucose tolerance
  • Low activity level (exercising less than 3 times a week)
  • Metabolic syndrome

  • A condition called acanthosis nigricans, which causes dark, thickened skin around the neck or armpits

Persons from certain ethnic groups, including African Americans, Hispanic Americans, Asian Americans, and Native Americans, have a higher risk for diabetes.

Everyone over 45 should have a blood sugar (glucose) test at least every 3 years. Regular testing of blood sugar levels should begin at a younger age, and be performed more often if you are at higher risk for diabetes.
